Szukana fraza: [Abstract = "This method allows describing the dynamics of this nonlinear system in an infinite dimensional space over a wide operating range. A stability analysis of the nonlinear Saint\-Venant PDE is proposed both by using Linear Matrix Inequalities \(LMIs\) and an Internal Model Boundary Control \(IMBC\) structure. The method is applied both in simulations and real experiments through a microchannel, illustrating thus the theoretical results developed in the paper."]
